Movement and barriers

Abstract

The present application discloses a movement and a barrier gate. The movement includes a mounting plate, a swinging member rotatably mounted on the mounting plate and used to connect to a gate rod, a lifting and lowering driving mechanism for driving the swinging member to rotate, a first lifting limiter provided on the mounting plate, a lowering limiter provided on the mounting plate, and a buffer spring provided on the swinging member; when the swinging member drives the gate rod to rotate to the highest point, the buffer spring abuts against the first lifting limiter, and when the swinging member drives the gate rod to rotate to the lowest point, the buffer spring abuts against the lowering limiter. By cooperating with the buffer spring and the first lifting limiter and the lowering limiter, buffering can be achieved when the movement drives the gate rod to rise and fall. The installation positions of the first lifting limiter and the lowering limiter are within the boundary range of the mounting plate, and the buffer spring is located on the swinging member, making the structure of the movement more compact. However, the method of setting a tension spring requires providing sufficient stretching space for the tension spring, which is not conducive to the miniaturization of the movement structure.

Description

Technical Field

[0001] The present application relates to the field of barrier gates, and in particular to a movement and a barrier gate. Background Art

[0002] Barrier gates, also known as vehicle barriers, are specialized entrance and exit management devices designed to restrict motor vehicle traffic on roads. They are widely used in highway toll booths and parking systems to manage vehicle access. Electric barriers can be raised and lowered independently via wireless remote control, or they can be automatically managed by parking management systems. Vehicles are released upon entry by card collection, and released automatically upon exit after parking fees are collected.

[0003] A barrier gate consists of a housing and a lever mounted on it. The mechanism within the housing drives the lever's rotation, thereby raising and lowering it. To extend the life of the barrier gate and prevent the lever from making loud noise during operation, a tension spring is typically installed between the mechanism and the lever to cushion the rise and fall of the lever. This ensures a more even speed and minimizes noise during the movement, which in turn protects the barrier gate from damage. However, the presence of a tension spring increases the vertical size of the mechanism, hindering its miniaturization. Summary of the Invention

[0004] The purpose of the present application is to provide a movement that can drive a gate rod to rise and fall, aiming to solve the problem in the prior art that a tension spring needs to be provided between the gate rod and the movement, resulting in a larger movement size.

[0007] In one embodiment, a buffer groove is formed on the surface of the swing member where the buffer spring is installed, and a gap is formed between the spring and the inner surface of the buffer groove.

[0008] In one embodiment, the depth of the buffer groove gradually decreases from the middle of the swing member to opposite ends of the swing member.

[0009] In one embodiment, the inner surface of the buffer groove is a curved surface.

[0010] In one embodiment, the buffer spring is detachably connected to the swing member.

[0011] In one embodiment, a first fixing threaded hole is provided at the opposite ends of the swinging member, a first fixing through hole is provided at the opposite ends of the buffer spring sheet, a first fixing screw is provided between the buffer spring sheet and the swinging member, and the first fixing screw passes through the first fixing through hole and is threadedly connected to the first fixing threaded hole.

[0012] In one embodiment, the first fixing through hole is an elongated hole.

[0013] In one embodiment, the first lifting limit member includes a first lifting positioning column fixedly connected to the mounting plate, and a first lifting positioning cylinder sleeved on the outside of the first lifting positioning column, and the first lifting positioning column is provided with a threaded hole (the first lifting positioning cylinder is rotatably connected to the first lifting positioning column).

[0014] In one embodiment, the movement further includes a second lifting limiter provided on the mounting plate, the first lifting limiter and the second lifting limiter are respectively located on opposite sides of the dropping limiter, and the dropping limiter is rotatably mounted on the mounting plate.

[0015] In one embodiment, the descent limit member has a limiting protrusion for contacting the buffer spring (the second lifting limit member includes a second lifting positioning column fixedly connected to the mounting plate, and a second lifting positioning cylinder sleeved on the outside of the second lifting positioning column, and the second lifting positioning column is provided with a threaded hole; the second lifting positioning cylinder is rotatably connected to the second lifting positioning column).

[0016] In one embodiment, the lifting and lowering drive mechanism includes a driving motor, a driving gear mounted on the output shaft of the driving motor, a driven gear rotatably mounted on the mounting plate and meshing with the driving gear, and a connecting rod connected between the driven gear and the swinging member; the connecting rod is rotatably connected to the driven gear, and the connecting rod is rotatably connected to the swinging member.

[0017] In one embodiment, the connecting rod member includes multiple first laminated plates, which are stamped to form the connecting rod member; the swing member includes multiple second laminated plates, which are stamped to form the swing member; the drop limit member includes multiple third laminated plates, which are stamped to form the drop limit member.

[0018] In one embodiment, the lifting and lowering drive mechanism also includes a rotating frame installed on the mounting plate; a rotating hole is opened on the mounting plate, the output shaft passes through the rotating hole and is rotatably installed on the rotating frame; the connecting rod is provided on both opposite sides of the driven gear.

[0021] The beneficial effects of the embodiments of the present application are as follows: When the lifting and lowering drive mechanism drives the swing member to rotate to a point close to its highest point, the buffer spring on the swing member abuts the first lifting stop. The first lifting stop applies pressure to the buffer spring, causing it to deform, thereby slowing the swing member's rotation and stopping it, thus cushioning the gate bar as it rises. When the lifting and lowering drive mechanism drives the swing member to rotate to a point close to its lowest point, the buffer spring on the swing member abuts the lowering stop. The lowering stop applies pressure to the buffer spring, causing it to deform, thereby slowing the swing member's rotation and stopping it, thus cushioning the gate bar as it descends. In other words, the mechanism in the embodiments of the present application, through the cooperation of the buffer spring with the first lifting stop and the lowering stop, can cushion the movement of the gate bar as it is driven by the mechanism. The first lifting stop and the lowering stop are mounted within the boundaries of the mounting plate, and the buffer spring is located on the swing member, making the mechanism structure relatively compact. However, the method of setting the tension spring requires providing sufficient stretching space for the tension spring, which is not conducive to the miniaturization of the movement structure.

[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0036] The implementation of this application is described in detail below with reference to specific embodiments.

[0037] like Figure 1-Figure 3 As shown, an embodiment of the present application proposes a movement 1000, including a mounting plate 1, a swinging member 2 rotatably mounted on the mounting plate 1 and used to be connected to a gate rod 13, a lifting and lowering driving mechanism 3 for driving the swinging member 2 to rotate, a first lifting limit member 4 provided on the mounting plate 1, a lowering limit member 5 provided on the mounting plate 1, and a buffer spring 6 provided on the swinging member 2; when the swinging member 2 drives the gate rod 13 to rotate to the highest point, the buffer spring 6 abuts against the first lifting limit member 4, and when the swinging member 2 drives the gate rod 13 to rotate to the lowest point, the buffer spring 6 abuts against the lowering limit member 5.

[0038] In the embodiments of this application, refer to Figure 4-Figure 5The lifting and lowering drive mechanism 3 drives the swing member 2 to rotate relative to the mounting plate 1, thereby driving the gate rod 13 connected to the swing member 2 to rotate, thereby achieving the lifting and lowering of the gate rod 13. When the lifting and lowering drive mechanism 3 drives the swing member 2 to rotate to a point close to the highest point (that is, when the gate rod 13 rotates to the highest point, for example, in the vertical state), the buffer spring 6 on the swing member 2 abuts the first lifting limiter 4. At this time, the first lifting limiter 4 applies pressure to the buffer spring 6, causing the buffer spring 6 to deform, thereby slowing down the rotation speed of the swing member 2 and stopping the swing member 2, completing the buffering of the gate rod 13 when it is raised. When the lifting and lowering drive mechanism 3 drives the swing member 2 to rotate to a point close to the lowest point (that is, when the gate rod 13 rotates to the lowest point, for example, when it is in a horizontal state), the buffer spring piece 6 on the swing member 2 abuts against the drop limiter 5. At this time, the drop limiter 5 applies pressure to the buffer spring piece 6, causing the buffer spring piece 6 to deform, thereby slowing down the rotation speed of the swing member 2 and stopping the swing member 2 from rotating, thereby completing the buffering of the gate rod 13 when it drops.

[0039] In other words, the mechanism 1000 of the present embodiment, through the cooperation of the buffer spring 6 with the first lift stopper 4 and the drop stopper 5, can achieve buffering when the mechanism 1000 drives the gate lever 13 up and down. The first lift stopper 4 and the drop stopper 5 are installed within the boundaries of the mounting plate 1, and the buffer spring 6 is located on the swing member 2, making the structure of the mechanism 1000 relatively compact. However, the use of a tension spring requires sufficient space for the tension spring to stretch, which is not conducive to the miniaturization of the mechanism 1000 structure.

[0040] See also Figure 2 As another specific embodiment of the movement 1000 provided herein, the swing member 2 has a buffer groove 201 formed on its surface for mounting a buffer spring 6. A gap is formed between the spring and the inner surface of the buffer groove 201. Therefore, when the buffer spring 6 deforms, it sinks into the buffer groove 201. The buffer spring 6 has sufficient deformation space to withstand high pressure and exerts a strong buffering force on the swing member 2 at the end of its rotation, causing the swing member 2 to stop rotating more smoothly.

[0041] See also Figure 2 As another specific embodiment of the movement 1000 provided herein, the depth of the buffer groove 201 gradually decreases from the middle portion of the swinging member 2 toward the opposite ends of the swinging member 2. Therefore, when the buffer spring 6 deforms and sinks into the buffer groove 201, the middle portion of the buffer spring 6 sinks the most into the middle portion of the chute (i.e., the middle portion of the swinging member 2), while the ends of the buffer spring 6 sink relatively less into the ends of the buffer groove 201. In other words, the buffer spring 6 deforms smoothly from the middle portion toward the ends, which facilitates providing a relatively smooth buffering force to the first lift stopper 4 and the lowering stopper 5.

[0042] See also Figure 2 As another specific embodiment of the movement 1000 provided in the present application, the inner surface of the buffer groove 201 is an arc surface. When the buffer spring 6 is deformed and sinks into the interior of the buffer groove 201, the buffer spring 6 can be in close contact with the inner surface of the buffer groove 201, which can avoid large local deformation of the buffer spring 6, and the buffer spring 6 is not easily damaged after long-term use.

[0043] See also Figure 3 As another specific embodiment of the movement 1000 provided in the present application, the buffer spring 6 is detachably connected to the swing member 2, and the buffer spring 6 can be replaced when the elastic performance of the buffer spring 6 decreases.

[0044] See also Figure 3 and Figure 5 As another specific embodiment of the movement 1000 provided herein, first fixing threaded holes are defined at opposite ends of the swing member 2, first fixing through holes 601 are defined at opposite ends of the buffer spring 6, and first fixing screws 7 are provided between the buffer spring 6 and the swing member 2. The first fixing screws 7 pass through the first fixing through holes 601 and are threadedly engaged with the first fixing threaded holes. The use of the first fixing screws 7 allows for quick assembly and disassembly.

[0045] See also Figure 3 and Figure 5 As another specific embodiment of the movement 1000 provided herein, the first fixing through-hole 601 is an elongated hole. Therefore, when the buffer spring 6 is subjected to force and is pressed into the buffer groove 201, the ends of the buffer spring 6 can also slide relative to the swing member 2 (the first fixing through-hole 601 is an elongated hole of a certain length, which can slide a certain distance relative to the first fixing screw 7, causing the ends of the buffer spring 6 to slide toward the center of the swing member 2), thereby supporting the buffer spring 6 to deform more fully. In this case, the first fixing screw 7 serves as a guide for the sliding of the buffer spring 6.

[0046] See also Figure 4 As another specific embodiment of the movement 1000 provided in the present application, the first lifting limiter includes a first lifting positioning column 401 fixedly connected to the mounting plate 1, and a first lifting positioning cylinder 402 sleeved on the outside of the first lifting positioning column 401. The first lifting positioning column 401 is provided with a threaded hole to facilitate cooperation with a screw, so that the mounting plate 1 is connected to the movement 1000 and other components of the gate through the first lifting positioning column 401, which facilitates the installation and fixation of the mounting plate 1. Optionally, (the first lifting positioning cylinder 402 is rotatably connected to the first lifting positioning column 401, and the first lifting positioning cylinder 402 is not easy to generate sliding friction with the buffer spring 6 when in contact with the buffer spring 6, thereby avoiding the occurrence of harsh sounds).

[0047] See also Figure 4 As another specific embodiment of the movement 1000 provided in the present application, the movement 1000 also includes a second lifting limiter 8 provided on the mounting plate 1, and the first lifting limiter 4 and the second lifting limiter 8 are respectively located on opposite sides of the dropping limiter 5, and the dropping limiter 5 is rotatably mounted on the mounting plate 1 (there is sufficient friction between the dropping limiter 5 and the mounting plate 1, and after the dropping limiter 5 is rotated to the preset position under force, it is not easy to loosen, and can better resist the buffer spring 6 on the swinging member 2; the dropping limiter 5 can also be fixed in a certain position using an external locking member).

[0048] At this time, the descent limiter 5 acts as a commutator, and it is necessary to make the movement 1000 drive the gate rod 13 to rise and fall on the right side: the end of the descent limiter 5 (the part facing the buffer spring 6) is rotated to bias towards the first lifting limiter 4, so that the swing member 2 moves to approach the highest point (that is, the gate rod 13 rotates to the highest point, for example, when it is in a vertical state), the buffer spring 6 on the swing member 2 abuts against the first lifting limiter 4. At this time, the first lifting limiter 4 applies pressure to the buffer spring 6, and the buffer spring 6 is deformed, thereby slowing down the rotation speed of the swing member 2, and stopping the swing member 2 from rotating, completing the buffering when the gate rod 13 rises. When the lifting and lowering drive mechanism 3 drives the swing member 2 to rotate to a point close to the lowest point (that is, when the gate rod 13 rotates to the lowest point, for example, when it is in a horizontal state), the buffer spring piece 6 on the swing member 2 abuts against the drop limiter 5. At this time, the drop limiter 5 applies pressure to the buffer spring piece 6, causing the buffer spring piece 6 to deform, thereby slowing down the rotation speed of the swing member 2 and stopping the swing member 2 from rotating, thereby completing the buffering of the gate rod 13 when it drops.

[0049] When the movement 1000 is required to drive the gate rod 13 to rise and fall on the left side: the end of the descent limit member 5 (the part facing the buffer spring 6) is rotated to bias towards the second lifting limit member 8, so that the swing member 2 moves to approach the highest point (that is, when the gate rod 13 rotates to the highest point, for example, when it is in a vertical state), the buffer spring 6 on the swing member 2 abuts against the second lifting limit member 8. At this time, the second lifting limit member 8 applies pressure to the buffer spring 6, and the buffer spring 6 is deformed, thereby slowing down the rotation speed of the swing member 2, and stopping the swing member 2 from rotating, completing the buffering when the gate rod 13 rises. When the lifting and lowering drive mechanism 3 drives the swing member 2 to rotate to a point close to the lowest point (that is, when the gate rod 13 rotates to the lowest point, for example, when it is in a horizontal state), the buffer spring piece 6 on the swing member 2 abuts against the drop limiter 5. At this time, the drop limiter 5 applies pressure to the buffer spring piece 6, causing the buffer spring piece 6 to deform, thereby slowing down the rotation speed of the swing member 2 and stopping the swing member 2 from rotating, thereby completing the buffering of the gate rod 13 when it drops.

[0050] Therefore, when the gate lever 13 needs to be switched between left-side and right-side elevation, the lowering stopper 5 (reverser) can be rotated to switch, making the switching operation relatively simple and convenient. Compared to changing the internal structure of the movement 1000 or the orientation of the chassis, the operation time and difficulty are greatly reduced. It is understood that when the gate lever 13 is lowered to the left, it is installed on the left side of the movement 1000; when the gate lever 13 is lowered to the right, it is installed on the right side of the movement 1000.

[0051] Specifically, when the right side is required to take off and land (left and right are defined as left and right on the front side of the figure), the end of the drop limiter 5 is rotated to deviate to the first lift limiter 4. At this time, the motion range of the swing member 2 is between the first lift limiter 4 and the drop limiter 5 ( Figure 1 In the range a shown in the figure, the end of the drop limiter 5 is closer to the buffer spring 6 on the swing member 2 relative to the second lift limiter 8. When the swing member 2 rotates, the buffer spring 6 first contacts the drop limiter 5 and is held against by the drop limiter 5, and cannot rotate to the second lift limiter 8. When the swing member 2 drives the gate rod 13 to rotate to the highest point, it abuts against the first lift limiter 4. When the swing member 2 rotates to the lowest point, it abuts against the drop limiter 5.

[0052] When the left side is required to rise and fall, the end of the drop limiter 5 is rotated to deviate to the second rise limiter 8. At this time, the motion range of the swing member 2 is between the second rise limiter 8 and the drop limiter 5 ( Figure 4 In the range b shown, the end of the drop limiter 5 is closer to the buffer spring 6 on the swing member 2 relative to the first lift limiter 4. When the swing member 2 rotates, the buffer spring 6 first contacts the drop limiter 5 and is held against the drop limiter 5, and cannot rotate to the first lift limiter 4. When the swing member 2 drives the gate rod 13 to rotate to the highest point, it abuts against the second lift limiter 8. When the swing member 2 rotates to the lowest point, it abuts against the drop limiter 5.

[0053] See also Figure 3-Figure 4 As another specific embodiment of the movement 1000 provided in the present application, the drop limiter 5 has a limit protrusion 501 for contacting the buffer spring 6. The limit protrusion 501 is located at the end of the drop limiter 5 and is used to abut against the buffer spring 6.

[0054] When the movement 1000 drives the gate lever 13 to rise or fall to the right, it rotates the stop protrusion 501 on the end of the drop stopper 5 toward the first rise stopper 4. At this time, the swing member 2 has a range of motion between the stop protrusions 501 on the first rise stopper 4 and the drop stopper 5. When the swing member 2 drives the gate lever 13 to rotate to its highest point, it abuts against the first rise stopper 4. When the swing member 2 abuts against the stop protrusion 501 on the drop stopper 5 at its lowest point, it abuts against the stop protrusion 501 on the drop stopper 5. When the gate lever 13 rises or falls to the right, after the swing member 2 abuts against the stop protrusion 501 on the drop stopper 5, it cannot continue to rotate toward the second rise stopper 8.

[0055] When the movement 1000 drives the gate lever 13 to rise or fall on the left side, it rotates the stop protrusion 501 on the end of the drop stop member 5 toward the second rise stop member 8. At this time, the movement range of the swing member 2 is between the second rise stop member 8 and the stop protrusion 501 on the drop stop member 5. When the swing member 2 drives the gate lever 13 to rotate to the highest point, it abuts against the second rise stop member 8. When the swing member 2 rotates to the lowest point, it abuts against the stop protrusion 501 on the drop stop member 5. When the gate lever 13 rises or falls on the left side, after the swing member 2 abuts against the stop protrusion 501 on the drop stop member 5, it cannot continue to rotate toward the first rise stop member 4.

[0056] See also Figure 4 , as another specific embodiment of the movement 1000 provided in the present application, (the second lifting limiter includes a second lifting positioning column 801 fixedly connected to the mounting plate 1, and a second lifting positioning cylinder 802 sleeved on the outside of the second lifting positioning column 801, and the second lifting positioning column 801 is provided with a threaded hole; the second lifting positioning cylinder 802 is rotatably connected to the second lifting positioning column 801 to facilitate cooperation with the screw, so that the mounting plate 1 is connected to the movement 1000 and other components of the gate machine through the second lifting positioning column 801, which is convenient for the installation and fixation of the mounting plate 1. Optionally, the second lifting positioning cylinder 802 is rotatably connected to the second lifting positioning column 801, and the second lifting positioning cylinder 802 is not easy to generate sliding friction with the buffer spring piece 6 when in contact with the buffer spring piece 6, thereby avoiding the occurrence of harsh sounds.).

[0057] See also Figure 5As another specific embodiment of the movement 1000 provided in the present application, the lifting and lowering drive mechanism 3 includes a driving motor 301, a driving gear 302 mounted on the output shaft 3011 of the driving motor 301, a driven gear 303 rotatably mounted on the mounting plate 1 and meshing with the driving gear 302, and a connecting rod 304 connected between the driven gear 303 and the swinging member 2; the connecting rod 304 is rotatably connected to the driven gear 303, and the connecting rod 304 is rotatably connected to the swinging member 2. The driving motor 301 drives the driving gear 302 to rotate, thereby driving the driven gear 303 meshing with the driving gear 302 to rotate. When the driven gear 303 rotates, it applies force to the connecting rod 304, causing the connecting rod 304 to apply force to the swinging member 2, thereby driving the swinging member 2 to rotate relative to the mounting plate 1. Optionally, the driven gear 303 may be a sector gear (that is, a circular gear with part of the structure missing, and the missing angle can be selected according to needs) to reduce the space occupied by the driven gear 303 and improve the compactness of the movement 1000 structure.

[0058] See also Figure 5 As another specific embodiment of the movement 1000 provided in the present application, the connecting rod 304 includes a plurality of first laminated plates 3041, which are stamped to form the connecting rod 304. The stamping process is relatively convenient, and different numbers of first laminated plates 3041 can be selected according to the thickness. Compared with mold opening and mold processing, as well as CNC processing, the processing can be relatively fast and the processing technology is relatively simple; the swinging member 2 includes a plurality of second laminated plates 202, which are stamped to form the swinging member 2. The swinging member 2 adopts stamping processing to stamp the plurality of second laminated plates 202 to form the swinging member 2. Different numbers of second laminated plates 202 are selected according to the thickness of the swinging part 2. Compared with the mold opening and mold processing, as well as CNC processing, the processing can be faster and the processing technology is simpler. The drop limiter 5 includes multiple third laminated plates 502, and the multiple third laminated plates 502 are punched to form the drop limiter 5. The drop limiter 5 is stamped to form the drop limiter 5. Different numbers of third laminated plates 502 can be selected according to the thickness of the drop limiter 5. Compared with the mold opening and mold processing, as well as CNC processing, the processing can be faster and the processing technology is simpler.

[0059] See also Figure 5As another specific embodiment of the movement 1000 provided in the present application, the lifting and lowering drive mechanism 3 also includes a rotating frame 9 installed on the mounting plate 1 (connected by bolts and other components, and forming a certain gap); a rotating hole 101 is opened on the mounting plate 1, and the output shaft 3011 passes through the rotating hole 101 and is rotatably mounted on the rotating frame 9. The gap between the rotating frame 9 and the mounting plate 1 is used to accommodate the output shaft 3011 and the driving gear 302 on the output shaft 3011. When the output shaft 3011 rotates, the rotating hole 101 and the rotating frame 9 serve as the base for rotation, thereby improving the stability of rotation; connecting rods 304 are provided on the opposite sides of the driven gear 303, and the connecting rods 304 on both sides are also rotatably connected to the two sides of the swinging member 2 respectively. Part of the driven gear 303 is inserted between the connecting rods 304 on both sides, so that the driven gear 303 can apply a relatively stable force to the whole composed of the connecting rods 304 on both sides, so that the connecting rods 304 can stably apply a rotational force to the swinging member 2. Therefore, when the driven gear 303 drives the swing member 2 to rotate through the connecting rod 304, the connecting rod 304 can tend to only apply the force required for rotation to the swing member 2, so that the swing member 2 tends to only rotate and is not prone to deflection perpendicular to the rotation direction, making the gate rod 13 of the barrier gate rotate more smoothly.
